Extendabond (also known as Proflex) tape is the best I've ever tried and I've used it for ages now. It doesn't break down at all for me and holds tight to the bitter end. It's a life saver. I use the mini tabs because they are really quick and easy to apply. I stick them to my scalp and then attach the piece. I love them! You can get it in long strips too. It's a little more expensive than some tapes but when you try it you will see why.
